Circuit topology and energy management method of satellite power source system

Abstract

The invention discloses a circuit topology and energy management method of a satellite power source system. The circuit topology comprises a high-frequency transformer, a plurality of power source modules, energy storage modules and load modules; the high-frequency transformer has a plurality of primary and auxiliary sides; and the power source modules, the energy storage modules and the load modules are connected with corresponding primary and secondary sides of the high-frequency transformer respectively through connecting terminals. According to the circuit topology of the invention, the high-frequency transformer is adopted, and therefore, the circuit topology is simple in circuit structure and control, has high power density and energy density, can simultaneously drive loads of different voltage levels and power levels load and can realize fault operation and coordinated control on power generation, energy storage and loads, and therefore, the circuit topology can be widely applied to high-frequency control systems such as a satellite power source system and a motor vehicle driving and energy management system.

Description

Technical field [0001] The present invention relates to the field of satellite power supply systems, in particular to a circuit topology and energy management method of a satellite power supply system. Background technique [0002] The satellite power system provides power supply for all the electrical equipment on the satellite. The reliability, stability and anti-interference ability of the satellite power system determines the operation status of the satellite and the realization of the satellite's complex functions. [0003] The traditional satellite power system connects multiple sets of solar panels in series and parallel, realizes centralized power supply through electronic power equipment such as PCU, and uses multiple secondary power supplies to convert the bus voltages of multiple sets of solar panels in series and parallel into each load. Grade voltage. The power supply system has a large number of power supplies, fault isolation, complex protection design, and cannot d...
